GRAIN-DOOR.

SPECIFICATION forming part of Letters Patent No. 500,963, dated July 4,1893.

Application filed August 30, 1892. Serial No. 444.566. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOHN SHERIDAN, residing at Quincy, in the county ofAdams and State of Illinois, have invented certain new and usefulImprovements in Grain-Doors and Ido hereby declare the following to be afull, clear, and exact description of the invention, such as will enableOthers skilled in the art to which it appertains to make and use thesame.

My invention relates to an-improvement in grain doors for cars and moreparticularly to an inside grain door,-the object of the invention beingto produce an inside grain door which shall be strong and durable, cheapto manufacture, easy to use, and effectual in the performance of itsfunctions.

A further object is to produce a grain door made in two (or more) parts,and to sO construct said door that one or both of said parts can beemployed, as desired, and so that when both parts are used there will beno danger of escape of grain between them.

With these objects in View the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figurel is Fig. 2 is a sectional view.Fig. 3 is a view of one of the socket castings.

A represents the door posts, each of which is made with a series(preferably two) of recesses, for the reception of socket pieces onThese socket pieces are preferably made of cast or malleable iron andeach is made with an open or inverted L-shaped slot or recess b. Ineffect these socket pieces produce hooks for the reception of earscwhich project from the ends of steel cross bars C, which latter arelocated on the inside of the sections of the door B.

The sections of the door B are preferabl made of sheet iron and at theirends Overlap and bear against the door postsA.

The upper section of the door is provided with a strip dwhich projectsdownwardly and overlaps the upper edge of the lower section, thuspreventing the escape of grain between the two sections. It is evidentthat instead of making the strip d on the upper section, it may be madeto project from the upper edge of the lower section. It will also beseen that the cross bars C not only serve as means for fastening thesections of the door in place, but they also greatly strengthen thesheet iron sections, for which reason they are made of steel.

The door thus constructed is exceedingly simple, may be regulated insize, is cheap in construction and at'the same time possessesa requisiteamount of strength and durability. It is easy to operate and effectualin the performance of its functions.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a grain door, the combination with vertical door posts havingL-shaped openings therein, the upper portions of which are horizontaland extend to one face or edge of each door post, of removable doorsectionsconstrueted to overlap each other at adjacent edges and providedwith projections adapted tO enter the Openings in the posts,substantially as set forth.

2. The combination with two door posts having recesses therein, ofsocket pieces in said recesses, a grain door madeinsections, a cross barextending from endto end of each section, and ears at the ends of saidcross bars adapted to enter said socket pieces,sub stantially as setforth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses. JOHN SHERIDAN.
